HOISTING AND DUlVlPING BUCKET;

SPECIFICATION forming part of Letters Patent N o. 665,061, dated J anual-u4 1, 1901.

i Application and August 28,1900. semi No. 28,342. N0 man T0 all whom t may concern:

Be it known that l, JOSEPH CARSON, acitizen of the United States of America, and a resident of the borough of' Manhattan, in the city of New York and State of New York, have invented certain new and useful Improvements in Receptacles for Transporting and Delivering Materials, of which the following is a specification. y

This invention relates to improvements in hoisting and dumping buckets. An example is the bucket used in transporting earth and .other material from the place where the same is excavated to the place of discharge, and my improved receptacle or bucket is intended for this as well as other uses, such as the transporting and delivery of rock, coal, moulders materials, &c. The receptacles in .use at present are either simple buckets arranged to turn over at the place of delivery and dump the material out of the top, (now become 4the bottom,) or buckets which have a bottom hinged to the side of the receptacle and so arranged thatwhen over the place of discharge the bottom is released by a trip-line and the contents allowed to fall out, or, finally, buckets made in two parts and hinged at the top, the division being on a vertical line. When over the place of discharge, the trip-line allows the two parts to separate and the contents, more or less, fall out. All these devices, however, are objectionable for Various reasons, particularly when using sticky material, such as moist clay, for they will not readily and com pletely discharge themselves. My invention overcomes this difficulty and provides a receptacle of such construction that when discharging it will empty itself completely and quickly, its design being such as offers no shoulder or obstruction of sufficient size toiuterfere with parts are hinged together at the bottom and the hoist-rope is connected with the receptacle at the top, so that the normal tension of the hoist-rope tends to draw the two. parts together. ceptacle at the bottom in such manner that when the hoist-rope is slackened and the triprope is drawn taut the tension of the trip-rope will tend to open the two parts of the recep- A trip-rope is connected to the rev tacle, which at the same time inv'erts itself.

As when inverted the two parts flare from each other and as there are no shoulders or flanges on the top (now become the bottom) lof' sufficient size to interfere with the free discharge of the content-s, even the stickiest f clays fall freely out of the receptacle, which quickly and 'thoroughly empties itself.

Referring to the drawings which accoml' pany the specification to aid the description and which show only one shape of the receptacle, Figure 1 is a vertical section of thereceptacle on a plane at right angles to that of.

varied as required'by the use to which the device is to be applied. For the transportation and delivery of ordinary excavated materials the cylindrical form shown in Fig. 1 is very suitable. The said parts A B have bottoms C D, and are hinged together at or near said bottoms by any suitable hinges E, as the straps and pintle shown. The top of each part is preferably reinforced by Semi-annular bands F G, respectively, and the inner ends of both parts of the band are curved back to form hooks fg, which are engaged by removable hooks or open loops h to hold lthe parts A B closed while filling the receptacle and when there may not be sufflcient tension on the hoist-rope to pull said parts together. After the receptacle is filled the hooks h are removed by a workman, and the receptacle is hoisted and transferred by the hoist-rope J, which is connected in any suitable manner, as by hook lo and ring c, with the chain K. Said chain K is connected with each part A B at or near the top thereof and at a point so that the tension of the hoist-rope transmitted through the chain shall tend to draw said parts together. In this manner the hoist- Fig. 3 is a bottom plan ICO rope holds the parts of the receptacleclosed` while being hoisted and transferred'to the place of discharge. A trip-rope M, led from any suitable point above the place of discharge,is connected in any suitable manner,as by the ring fm, with the tripchain N, which is connected with each part A B at or near the bottom thereof, and at such point with respect to the hinges E that tension yon `the trip-rope tends to open the parts A B. To

guide the parts A B together when closed, side pieces or lugs O are provided, as shown.K The filled receptacle having reached the place of discharge, the trip-rope M is pulled, the hoist-rope J being at the same time slackened. The weight of the receptacle nowcoming on the said trip-rope. the receptacle inverts, the two parts A B at the same time opening and:

allowingthecontentstofallfreelyout. When the receptacle is emptied, the trip-rope is slackened and the hoist-rope pulled, righting' the receptacle and drawing the parts A B together, the lugs O guiding them to place.

It will be evident from the foregoing description that my invention may be used for many purposes, among others for transporting and simultaneously molding melders materials,

for the receptacle may be given the shape ofA tacle consisting of two parts hinged at the bottom and adapted when closed to contain the material and when opened and inverted to discharge the same, a hoist-rope attached to said receptacle and means to invert said receptacle when suspended from the hoistrope, substantially as described.

2. The combination of a two-part receptacle, said parts being hinged at the bottom, and a hoist-rope connected with said parts above the center of gravity of the filled receptacle and adapted to normally draw the parts together, substantially as described.

3. The combination of a receptacle consisting of two parts hinged together at the bottom, a hoist-rope connected with said parts above the centerof gravity of `theloaded receptacle, and a trip-rope connected with said parts below the said center of gravity, whereby said hoist-rope tends to hold the receptacle upright and with its parts closed, and the trip-ropetends to invert said receptacle and open its parts,.substantially as described.

4. The combination of a two-part receptacle, a hoist-rope, connection therefrom to each part of the receptacle at points above the center of gravity of the loaded receptacle and on opposite sides of the joint between said parts, a tripline, and a connection therefrom to each ot' said parts below said center of gravity and on opposite sides'o'f the hinge, substantially as described.

5. The combination of a two-part receptacle hinged at the bottom, a hoist-rope connected with said parts above the center of gravity of the loaded receptacle and on opposite sides of the joint between the parts, a device for holding said parts together when desired, and guides to bring said parts properly together when closing, substantially as described.
